This week we continued to take screen shots and input them into Google Earth.

Today showed a decent number of boats traveling through the shipping lanes and not too many outside the designated area.

Our worse case scenario still appears to be October 12th.

This week Dave showed Shannon and I how to take our screenshots and put them into an animation. This animation can be found earlier in the blog posted on November 24th.

Norus Summary

Monday, November 30th, 2009

Hallo
Over the past week Dani, Colin, Nelsen, and myself participated in the second NORUS workshop at Cal Poly in San Luis Obispo. Over the course of the week we were able to introduce others to the glider technology, learn about the REMUS and IVER2 Auvs the Crawler and another ROV. We were also able to connect with students from all over the world to learn about what they were studying, and how we could help them! For more information on the NORUS program please see our website at www.NORUS-science.com .

ha det og takker (norwegian for good bye and thank you)!

Hello all-

During our weekly meeting, we were asked by Josh and Scott about the waves.  We checked on our buoy, Capo Silleiro, only to discover that it hasn't been working since last Thursday.  We used another deep water buoy, Estaca de Bares--the northern most buoy in Spain--for our wave measurements:

Significant Wave Heights

If we were to simply look at these graphs, we would conclude that the waves would not vary much.  They would stay at 4 m high with a period of 8 seconds.  However, we looked at wave predictions provided by Puertos del Estados, which predicted something VERY different:

In 48 hours...

In 48 hours...

In 60 hours...

In 60 hours...

In 72 hours...

In 72 hours...

We do not know how accurate this is because two deep water buoys along the coast are down and incorrect.  If we assume that the other deep water buoys are accurate, however, we can predict that the waves will be horrendous (around 5-6 meters, or 15-18 feet).  If we were to make a suggestion, we would suggest retrieving the glider as fast as possible, otherwise lives may be at risk during the recovery.

Predictions For January and A Movie For Us All

Monday, November 30th, 2009

This week Marcus and Kaycee worked on the glider video and continued to watch Drake's movement in the Atlantic.  We found that one our previous predictions (pink path) is appears to be accurate so far and an eddy has appeared in the south and could cause a different path.  Drake also slowed down from 0.11m/s to 0.10m/s making its travel distance 2678400m by January.  We will continue to monitor its path.
